The Jubilee, Or Twentieth-Century, Cut

(via Diamond Cuts in Historic Jewelry:1381-1910) Herbert Tillander writes:

The short-lived Jubilee Cut is said to have been created in the United States in honor of Queen Victoria’s Golden Jubilee. The Jubilee itself was in 1897 but the cut did not appear until the beginning of the twentieth century. It is variously described, but appears to have been applied mainly to rough which was too thin for a well-made Brilliant. The illustrations are based on an actual gem weighing 2.63 ct, with a diameter of 8.85 x 8.95 mm and an overall height of 5.45 mm. It is slightly tinted J (Crystal) and somewhat scratched and abraded by wear. It could, however, be restored to flawless condition with very little loss of weight.

This cut may be described as an elaborate extension of the historical Pointed Star Cut, with five concentric rows of interlocking facets. The crown and the pavilion, though possessing forty facets each, are of totally different design from each other.
